Title: Solid immersion mirror and reproducing device
Inventor: HATANO HIROSHI
IPC: G02B17/08
Filed: 2000-08-17
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a reflection surface in a solid immersion mirror(SIM) to condense divergent light made incident. SOLUTION: In the SIM 201 to make light from an optical fiber 22 incident on a medium 210 as the divergent light 7 and to condense at a condensing point 231, the shape of a sideward reflection surface 240 is made as a curved surface obtained by rotating an ellipse by centering a major axis, and two focal positions of the ellipse are set as an incident point 221 and the condensing point 231. The divergent light 7 made incident from the incident point 221 is reflected once by the sideward reflection surface 240 and is condensed at the condensing point 231. Then, the light is condensed without using the lower surface 230 of the medium 210 as a reflection surface. Thus, the damage of the reflection surface is not caused even though the lower surface 230 is damaged, so that the condensing of the light is not affected.

Title: Optimum load control system for compressor
Inventor: IWATANI JUNJI
IPC: F02C7/057
Filed: 2000-08-18
Abstract: PROBLEM TO BE SOLVED: To provide an optimum load control system for compressors, permitting the use at a high pressure ratio by controlling the loads of stages in the axial direction to be averaged and flattened. SOLUTION: The pressures of the stages of compressors are measured by using wall pressure sensors 1-8 and input to a computer 10 via an amplifier 9. The computer 10 selects the stage having the highest load from these signals and controls the stagger angle of a stationary vane upstream of this stage to be larger (closed) via an actuator 11. Therefore, the load of the selected stage is lowered. With the repetition of the operation in sequence, the loads of the stages in the axial direction can be flattened. The computer raises a pressure ratio in the range of not exceeding a preset estimated limiting value and flattens load distribution in the axial direction, permitting the use at a high pressure ratio.

Title: Method and equipment for optical transmission for optical fiber transmission system
Inventor: KONDO MASAKATSU
IPC: H04N5/00
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmitter which is free from secondary strains. SOLUTION: A series of optical fiber transmission system composed of optical transmitters 10, optical fibers 20, optical receivers 30, BPFs 40, and mixers 50 is designed to divide wide-band signals to be transmitted into a plurality of divided-band signals under a condition where the upper limited frequency does not exceed the twofold of the lower cut-off frequency on a frequency spectrum so that each divided band will not overlap secondary strain band (a differential beat band and a summed beat band) which occur in the transmission system. The transmission system transmits each divided-band signal. Consequently, the optical receivers 30 receive the divided bands separately from secondary strain bands on the frequency spectrum. Thereafter, the BPFs 40 intercept the secondary strain bands, namely, only extract the divided-band signals. Finally, the mixers 50 restore the original wide-band signals by mixedly piling up the extracted divided-band signals upon another. Therefore, the wide- band signals are transmitted without secondary strains.
